mLDP Inband Signaling - PIM Enable

Multipoint LDP in-band signaling allows you to carry multicast traffic across an existing IP/MPLS backbone, while avoiding the use of Protocol Independent Multicast (PIM) in the provider core. On the label edge router (LER), you can use this feature to enable PIM to use multipoint LDP in-band signaling for the upstream neighbors when the LER does not detect a PIM upstream neighbor.
